Flammability and Explosibility

Nonflammable

Check Digit Verification of cas no

The CAS Registry Mumber 42978-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,7 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42978-66:
(7*4)+(6*2)+(5*9)+(4*7)+(3*8)+(2*6)+(1*6)=155
155 % 10 = 5
So 42978-66-5 is a valid CAS Registry Number.
